I LID-SUPPORT FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Sept. 14, 1920.

Application filed January 15, 1919. Serial No. 271,219.

To all 'whoin'it may concern:

Be it known that I, JOHN Hnnzoo, a citi-- zen of the United States,residing at Saginaw, in the county of Saginaw and State of Michigan,have invented certain new and useful .Im rovements in Lid-Supports forTalking Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will a hinged lidin open position and for releas- 'ing the holding device to permit thelid to be, closed, the functions of supporting the lidin open positionand of releasing it and permitting it to be closed being performed bymerely opening and closingthe lid itself, without separatelymanipulating the deyice by which the lid is locked or released.

A further object is to provide a lid support having but one pivotedpartcapab e of performing the foregoing functions-without noise or rattling.

With these and other objects in view which will appear later in thespecification, my invention consists in the devices described andclaimed, and the equivalents thereof. v

In the drawings, Figure 1 is a side view, broken away in part, showingthe lid and upper part of a talking machine cabinet with my lid-holdingdevice attached, the'device being shown in its closed position.

Fig. 2 is a similar view, showing the lid in its open position andsupported by the said device.

Fig. 3 is an enlarged side view of the lid- 1 so porting arm.

ig. 4 is a similar view, broken away in part, showing the position ofthe arm relative to the stop pin when the lid is locked in its openposition.

Fig. 5 is an edge view, showing the device attached to the lid of acabinet, the parts of the lid and qabinet body being indicated in crosssection.

Figs. 6 and 7 are fragmentary side views of modified forms of heads, thesuccessive positions of the stop pin with relation to the head of thearm being indicated in dotted lines in Fig. 7.

device consists in the usual body 1 with its hmged 11d 2. Un the lid andnear one edge As is clearly shown in the drawings the thereof, asindicated in Fig. 2, is an arm 3 pivoted at one end to a pintle 4.

A: pro ect1ng supporting-pin or stop-pin 5, which ma be of any suitablecross-sectional shape 18 fixed on the body 1.

The other end of arm 3 is enlarged to form a fiat head 6, a preferredform of which is illustrated in Figs. 1 to 5 inclusive, in which thehead. 6 is formed with an irregularshaped groove or channel 7, or itsequivalent, the walls of the channel formlng a series of suitablydisposed cam-acting guides and stops, whereby the desired successivelongitudinal and lateral movements of the arm 3 are controlled when thelid is raised and lowered.

Head 6 may be ofiset to form aprojection as 8, in which one end ofgroove 7 may terminate, as shown in Figs. 3 and 4. The pintle 4 andstop-pin 5 are preferably so located with respect to each other that thearm,

3 normally presses by gravity or otherwise against and slides along thestop pin 5. Thus arm 3 normally tends to move toward the pin, that is,toward the left in Fig. 3 as and when permitted by the said guides andstops on head 6, and its lateral movements take place automatically.

In the operation of the preferred form- Figs. 1 to 5'-the lid is openedalmost to its fullest extent, the stop-pin entering groove 7 at theprojection 8. The pin is automatically guided into a niche 10, asindicated in Fig. 4, by the automatic lateral movement of arm 3. The lidis then released by the operator and is held open by pin 5.

Whe the lid is again opened slightly the niche 10 leaves the pin 5 andarm 3 automatically swings laterally until the wall of the upwardlyextending part of groove 7 engages the pin. Then upon closing the lidthe side wall of the groove 7 slides along the pin until the pin passesout at the upper end of the groove. Arm 3 then rests against the pin, asshown at 5 in Fig. 3, and slides along the pin while the lid closes.

During the initial lid opening movement of the arm 3 the pin isprevented from entering the upper end of groove 7 by a spring 9 or itsequivalent carried by head 6, the free end of the spring 9 overlappinthe exit opening of groove 7. During t e closing I movement of the lid,when the arm 3 is lowferred form of my device I have referred to 7 as agroove or its equivalent, and in practice I prefer to form it byrabbetin the face of the head 6, as shown in Fig. 3. owever, I maydispense with certain non-operating parts of the groove walls, utilizing onl such walls as actually operate as guides an stops for pin 5, toproperly control thesuccessive longitudinal and lateral movements of arm3, as in the modified form illustrated in Figs. 6 and 7.

In the form shown in Fig. 6, 11 is a stop that checks the lid-openingmovement of the arm and 12 is a projection that checks the succeedingautomatic lateral movement of the arm and guides the pin into niche 10,a side of which is formed b a downward projection 13. The lid is t ussupported in raised position by the pin. Subsequent opening of the lidlifts projection 13 clear of the pin and the arm 3 swings laterallyuntil the guide wall 14 strikes the pin and checks the lateral movementof the arm; Upon closing the lid, wall 14 slides along the wood or othersuitable mate-' I claim and desire to secure by Letters Patent is:

A lid support for cabinets and the like comprising in combination, aprojecting pin on the body of said cabinet, a dependlng arm pivotallgattached to the lid and yieldingly presse against and slidingly engagingsaid pin, a flat head. on said arm, said head formed with an offset, aspring secured to the head at one side thereof and above said offset,said head formed with a channel in one face thereof, adapted to receivethe end of said pin, said channel of irregular shape, one endterminating in the offset and the other end terminating under thespring,

the walls of the intermediate part of the I channel forming guides forthe pin and including a niche to receive said pin when the lid is in itsraised position.

In testimony whereof, I aflix m signature.

JOHN ERZOG.
